Referring to FIG. 1, FIG. 1 schematically illustrates an architecture diagram of a system for adjusting transmission resource according to an embodiment of the present disclosure. The system provided in the embodiment includes a User Equipment (UE) 101 and a network equipment 102.

Wherein, the UE 101 refers to an electronic equipment that can access the network equipment 102 through a wireless communication network, including a mobile terminal, a tablet computer, a wearable device, a vehicle-mounted terminal, and the like. The implementation manner of the UE 101 is not particularly limited in the embodiment, as long as the UE 101 can receive data transmitted from the network equipment 102.

The network equipment 102 includes to a public mobile communication network equipment, that is, an interface equipment for the UE 101 to access the Internet, and also one form of a radio station. It refers to a radio transceiver station that transmits information with the UE 101 in a certain radio coverage area.

In the embodiment of the present disclosure, the UE 101 communicates with the network equipment 102 through a wireless communication network, the method for adjusting transmission resource in the embodiment of the present disclosure may be executed by the UE 101 or the network equipment 102, or the method may be executed jointly by the UE 101 and the network equipment 102. For example, in some embodiment, the network equipment 102 may transmit a notification information to the UE 101; after receiving the notification information, the UE 101 may execute a corresponding tasks based on the notification information. Detailed description is given below by using detailed embodiments.

FIG. 2 schematically illustrates a first flowchart of a method for adjusting transmission resource according to an embodiment of the present disclosure. The method is executed by the network equipment 102 as shown in FIG. 1. As shown in FIG. 2, the method includes S201 and S202.

In S201, the network equipment allocates a second transmission resource for a first data based on a time difference, in response to the time difference between a predicted starting moment for a UE to receive the first data and a starting moment of a preconfigured first transmission resource for receiving the first data being determined greater than or equal to a preset time span, wherein the second transmission resource and the first transmission resource have different time domain resources, and the second transmission resource and the first transmission resource have a same frequency domain resource.

Wherein, in a Semi-Persistent Scheduling (SPS), after the UE applies for a transmission resource once, the network equipment periodically allocates the transmission resource to the UE within a period of time, and the UE uses the transmission resource allocated by the network equipment to receive data every period.

It should be understood that when a time difference between a starting moment for the UE to receive a first data that is available for transmission in a certain period and a starting moment of a first transmission resource for receiving the first data is greater than or equal to a preset time span, it indicates that the starting moment for receiving the first data is earlier or later than the starting moment of the first transmission resource, in this case, the first data cannot be transmitted through the first transmission resource in time, so that the UE cannot receive the first data at the first time, and there is a certain delay.

In the embodiment of the present disclosure, in order to solve the above-mentioned problem, the network equipment may predict in advance whether the time difference between the starting moment for the UE to receive the data that is available for reception in each period and the starting moment of the transmission resource for receiving the data is greater than or equal to the preset time span. When a time difference between a starting moment for the UE to receive a first data that is available for transmission in a certain period and a starting moment of a first transmission resource for receiving the first data is greater than or equal to the preset time span, the network equipment allocates the second transmission resource for the first data based on the time difference, wherein the second transmission resource and the first transmission resource have different time domain resources, but a same frequency domain resource.

Wherein, the starting moment of the second transmission resource and the predicted starting moment for receiving the first data are the same, or a time difference between the starting moment of the second transmission resource and the predicted starting moment for receiving the first data is less than the preset time span.

In S202, the network equipment transmits a notification information to the UE, and the notification information is used for notifying the UE to update the first transmission resource to the second transmission resource.

In the embodiment of the present disclosure, after allocating the second transmission resource, the network equipment transmits the notification information to the UE, the notification information is used for notifying the UE to update the first transmission resource to the second transmission resource, so that the UE can receive the first data through the second transmission resource but not through the first transmission resource.

It should be understood that, if the starting moment of the second transmission resource is the same as the predicted starting moment for receiving the first data, or the time difference between the starting moment of the second transmission resource and the predicted starting moment for receiving the first data is less than the preset time span, the first data may be transmitted through the second transmission resource in time, so the delay in receiving the first data by the UE can be effectively eliminated or reduced.

In the embodiment of the present disclosure, the method for adjusting transmission resource is applied at the network equipment side. When a network equipment determines a time difference between a predicted starting moment for a UE to receive the first data UE and a starting moment of a preconfigured first transmission resource for receiving the first data is greater than or equal to a preset time span, the network equipment allocates a second transmission resource for the first data based on the time difference; wherein the second transmission resource and the first transmission resource have different time domain resources, and the second transmission resource and the first transmission resource have a same frequency domain resource; and the network equipment transmits a notification information to the UE for notifying the UE to update the first transmission resource to the second transmission resource and receive the first data on the second transmission resource. Therefore, the UE does not need to receive the first data on the first transmission resource, thereby effectively eliminating or reducing the delay generated when the UE receives the first data.

Further, based on the content described in the foregoing embodiment, referring to FIG. 3, FIG. 3 schematically illustrates a second flowchart of a method for adjusting transmission resource according to an embodiment of the present disclosure, and the method is executed by the network equipment 102 as shown in FIG. 1. In the embodiment of the present disclosure, the method includes S301 and S302.

In S301, the network equipment allocates a second transmission resource for a first data based on a time difference, in response to the time difference between a predicted starting moment for a UE to receive the first data and a starting moment of a preconfigured first transmission resource for receiving the first data being determined greater than or equal to a preset time span, wherein the second transmission resource and the first transmission resource have different time domain resources, and the second transmission resource and the first transmission resource have a same frequency domain resource.

Wherein, the content described in S301 is basically the same as the principle of the technical solution described in S201 in the foregoing embodiment. For details, reference may be made to the content described in the foregoing embodiment, which will not be repeated here.

In S302, the network equipment transmits a notification information to the UE, the notification information is used for notifying the UE to update the first transmission resource to the second transmission resource. The notification information includes a time indication information, and the time indication information is used for indicating a time shift of a starting moment of the second transmission resource relative to the starting moment of the first transmission resource.

In the embodiment of the present disclosure, after allocating the second transmission resource, the network equipment determines a time shift of a starting moment of the second transmission resource relative to the starting moment of the first transmission resource, and transmits the time shift to the UE through the notification information. The UE may determine the time shift of a starting moment of the second transmission resource relative to the starting moment of the first transmission resource based on the time shift, and determine the starting moment of the second transmission resource based on the starting moment of the first transmission resource and the time shift.

For example, assuming that the starting moment of the first transmission resource is T1, and the starting moment of the second transmission resource is T2, a notification information transmitted to the UE from the network equipment including a time indication information, the time indication information is used for indicating a time shift T (T=T1−T2) of a starting moment of the second transmission resource relative to the starting moment of the first transmission resource. After receiving the time indication information, the UE may determine the starting moment T2 of the second transmission resource based on the time shift and the starting moment T1 of the first transmission resource, that is, T2=T+T1.

Wherein, if sizes of the first transmission resource and the second transmission resource are the same, the UE may also determine an ending moment of the second transmission resource based on the starting moment and an ending moment of the first transmission resource and the determined starting moment of the second transmission resource, and determine the second transmission resource.

If the size of the first transmission resource is different from the size of the second transmission resource, the UE needs to determine a difference in the time domain between the first transmission resource and the second transmission resource, and then the UE may determine the ending moment of the second transmission resource based on the starting moment and the ending moment of the first transmission resource, the determined starting moment of the second transmission resource and the difference, thereby determining the second transmission resource.

Wherein, in an embodiment of the present disclosure, the time indication information may be a specific time shift determined by the network equipment directly, and the time shift is a time shift of the starting moment of the second transmission resource relative to the starting moment of the first transmission resource.

Specifically, after determining the time difference between the predicted starting moment for the UE to receive the first data and the starting moment of the first transmission resource, the network equipment may determine a time shift based on the time difference, and transmit the time shift to the UE as the time shift of the starting moment of the second transmission resource relative to the starting moment of the first transmission resource.

For example, the network equipment transmits a notification information to the UE, the notification information includes a time shift, and the time shift includes a determined time shift of the starting moment of the second transmission resource relative to the starting moment of the first transmission resource.

In another embodiment of the present disclosure, the time indication information may include an index of a time shift, and the index of the time shift includes a time shift of the starting moment of the second transmission resource relative to the starting moment of the first transmission resource.

Specifically, the UE may pre-configure a plurality of possible time shifts, after determining the time difference between the predicted starting moment for the UE to receive the first data and the starting moment of the preconfigured first transmission resource for receiving the first data, the network equipment may search for a time shift that is closest to the time difference among the plurality of possible time shifts preconfigured by the UE, and transmit an index of the searched time shift to the UE. After receiving the index, the UE may determine a particular time shift from the preconfigured plurality of time shifts based on the index, and determine the particular time shift as a time shift of the starting moment of the second transmission resource relative to the starting moment of the first transmission resource.

For example, a UE may pre-configure a plurality of possible time shifts t1, t2, t3, t4 and t5, after determining a time difference between a predicted starting moment for the UE to receive a first data and a starting moment of a preconfigured first transmission resource for receiving the first data, if the time shift t3 is determined as a time shift which is closest to the time difference, a network equipment transmits an index corresponding to the t3 to the UE. After receiving the index, the UE determines the time shift t3 based on the index, and determines the time shift t3 as a time shift of the starting moment of the second transmission resource relative to the starting moment of the first transmission resource.

In the embodiment of the present disclosure, the network equipment may determine a time shift directly as the time shift of the starting moment of the second transmission resource relative to the starting moment of the first transmission resource, based on the time difference between the predicted starting moment for the UE to receive the first data and the starting moment of the preconfigured first transmission resource for receiving the first data. The network equipment may also determine one time shift from the plurality of possible time shifts preconfigured by the UE as the time shift of the starting moment of the second transmission resource relative to the starting moment of the first transmission resource, based on the time difference between the predicted starting moment for the UE to receive the first data and the starting moment of the preconfigured first transmission resource for receiving the first data. And the implementation process is more flexible.

According to the method for adjusting transmission resource provided in embodiments of the present disclosure, after allocating the second transmission resource for the first data, the network equipment may transmit the time shift of the starting moment of the second transmission resource relative to the starting moment of the first transmission resource to the UE. The UE may determine the starting moment of the second transmission resource based on the time shift, update the first transmission resource to the second transmission resource based on the starting moment of the second transmission resource, and receive the first data on the second transmission resource.

Further, based on the content described in the foregoing embodiment, referring to FIG. 4, FIG. 4 schematically illustrates a third flowchart of a method for adjusting transmission resource according to an embodiment of the present disclosure, and the method is executed by the network equipment 102 as shown in FIG. 1. In an embodiment of the present disclosure, the method includes S401 and S402.

In S401, the network equipment allocates a second transmission resource for a first data based on a time difference, in response to the time difference between a predicted starting moment for a UE to receive the first data and a starting moment of a preconfigured first transmission resource for receiving the first data being determined greater than or equal to a preset time span, wherein the second transmission resource and the first transmission resource have different time domain resources, and the second transmission resource and the first transmission resource have a same frequency domain resource.

Wherein, the content described in S401 is basically the same as the principle of the technical solution described in S201 in the foregoing embodiment. For details, reference may be made to the content described in the foregoing embodiment, which will not be repeated here.

In S402, the network equipment transmits a notification information to the UE, the notification information is used for notifying the UE to update the first transmission resource to the second transmission resource. The notification information includes a starting moment of the second transmission resource.

In the embodiment of the present disclosure, after determining that the time difference between the predicted starting moment for the UE to receive the first data and the starting moment of the preconfigured first transmission resource for receiving the first data is greater than or equal to a preset time span, the network equipment allocates the second transmission resource for the first data based on the time difference, and transmits the starting moment of the second transmission resource directly to the UE through the notification information. After receiving the notification information, the UE may determine the second transmission resource based on the starting moment of the second transmission resource, and receive the first data on the second transmission resource.

Wherein, if sizes of the first transmission resource and the second transmission resource are the same, the UE may also determine an ending moment of the second transmission resource based on the starting moment and an ending moment of the first transmission resource and the starting moment of the second transmission resource, and determine the second transmission resource.

If the size of the first transmission resource is different from the size of the second transmission resource, the UE needs to determine a difference in the time domain between the first transmission resource and the second transmission resource, and then the UE may determine the ending moment of the second transmission resource based on the starting moment and the ending moment of the first transmission resource, the starting moment of the second transmission resource and the difference, thereby determining the second transmission resource.

According to the method for adjusting transmission resource provided in embodiments of the present disclosure, after allocating the second transmission resource for the first data, the network equipment may transmit the starting moment of the second transmission resource to the UE. The UE may update the first transmission resource to the second transmission resource based on the starting moment of the second transmission resource, and receive the first data on the second transmission resource.

Further, based on the content described in the foregoing embodiment, in an embodiment of the present disclosure, the notification information may be a Downlink Control Information (DCI).

Wherein, the notification information may include an index of the first transmission resource. For example, if the notification information is a DCI, an Index indication may be included in the DCI for indicating a position of the first transmission resource, for example, the Index indication is used for indicating which set of transmission resource the first transmission resource belongs to (one UE may configure a plurality of sets of transmission resource at a same time).

In another embodiment of the present disclosure, the notification information may also include a relative position information between the first transmission resource and a current transmission resource for transmitting the notification information.

Wherein, the relative position information includes a number of resource blocks in a spacing between the first transmission resource and the current transmission resource.

Specifically, after receiving the DCI, the UE may determine a latest block of transmission resource after the current transmission resource for transmitting the DCI, or a N-th block of transmission resource after the current transmission resource as the above-mentioned first transmission resource. Wherein, the value of N may be agreed upon in a protocol or notified to the UE from the network equipment through the notification information, for example, the value of N is directly indicated in the DCI.

In the embodiment of the present disclosure, after determining that the time difference between the predicted starting moment for the UE to receive the first data and the starting moment of the preconfigured first transmission resource for receiving the first data is greater than or equal to the preset time span, the network equipment may transmit the index of the first transmitting resource and/or the relative position information between the first transmission resource and a current transmission resource to the UE, which makes the UE can determine the first transmission resource based on the index and/or the relative position information.

In an embodiment of the present disclosure, the notification information may be a Down Link Medium Access Control Control Element (DL MAC CE) information.

Wherein, a DL MAC CE information may be transmitted on the current transmission resource, the DL MAC CE information may include a time indication information for the next transmission resource, the time indication information is used for indicating a time shift of an actual starting moment of the next transmission resource relative to a preconfigured starting moment of the next transmission resource.

In the embodiment of the present disclosure, the network equipment may transmit the time indication information for the next transmission resource to the UE through the DL MAC CE information, which ensures that the starting moment for the UE to receive data next time is the same as or close to the starting moment of the next transmission resource, thereby reducing or eliminating the delay generated by the UE when receiving data.

Further, in an embodiment of the present disclosure, a method for adjusting transmission resource is provided, referring to FIG. 5, FIG. 5 schematically illustrates a fourth flowchart of a method for adjusting transmission resource according to an embodiment of the present disclosure, and the method is executed by the UE 101 as shown in FIG. 1. As shown in FIG. 5, the method includes S501, S502 and S503.

In S502, the UE updates the first transmission resource to the second transmission resource based on the notification information.

In S503, the UE receives data on the second transmission resource.

In the embodiment of the present disclosure, the network equipment may predict in advance whether the time difference between the starting moment for the UE to receive the data that is available for transmission in each period and the starting moment of the transmission resource for receiving the data is greater than or equal to the preset time span. When a time difference between a starting moment for the UE to receive a first data that is available for transmission in a certain period and a starting moment of a first transmission resource for receiving the first data is greater than or equal to the preset time span, the network equipment allocates the second transmission resource for the first data based on the time difference, wherein the second transmission resource and the first transmission resource have different time domain resources, but a same frequency domain resource.

Wherein, after allocating the second transmission resource, the network equipment transmits the notification information to the UE. After receiving the notification information transmitted by the network equipment, the UE updates the first transmission resource to the second transmission resource based on the notification information, and receives the first data through the second transmission resource but not through the first transmission resource.

The UE no longer receives the first data through the first transmission resource means that the UE no longer performs reception and decoding on the first transmission resource, and no longer performs feedback on the first transmission resource, which effectively avoids a waste of transmission resource and an unnecessary energy consumption.

It should be understood that, if the starting moment of the second transmission resource is the same as the predicted starting moment for receiving the first data, or the time difference between the starting moment of the second transmission resource and the predicted starting moment for receiving the first data is less than the preset time span, the UE may receive the first data through the second transmission resource in time, so the delay in receiving the first data by the UE can be effectively eliminated or reduced.

Wherein, functions that can be implemented by the UE in the embodiment of the present disclosure are the same as functions that can be implemented by the UE in the embodiment described in FIG. 2 in the above-mentioned embodiment, reference may be made to the content described in the foregoing embodiment, which will not be repeated here.

After receiving the notification information transmitted from the network equipment, the UE updates the first transmission resource to the second transmission resource, and receives the first data on the second transmission resource but not on the first transmission resource, which effectively eliminates or reduces a delay generated when the UE receives the first data.

In an embodiment of the present disclosure, the notification information includes a time indication information, and the time indication information is used for indicating a time shift of the starting moment of the second transmission resource relative to the starting moment of the first transmission resource.

Wherein, the UE updates the first transmission resource to the second transmission resource based on the notification information in S502 includes Sa1, Sa2 and Sa3.

Specifically, the UE may pre-configure a plurality of possible time shifts, after determining the time difference between the predicted starting moment for the UE to receive the first data and the starting moment of the preconfigured first transmission resource for receiving the first data, the network equipment may search for a time shift that is closest to the time difference among the plurality of possible time shifts preconfigured by the UE, and transmit an index of the searched time shift to the UE. After receiving the index, the UE may determine a particular time shift from the preconfigured plurality of time shifts based on the index, and determine the particular time shift as a time shift of the starting moment of the second transmission resource relative to the starting moment of the first transmission resource.

For example, a UE may pre-configure a plurality of possible time shifts t1, t2, t3, t4 and t5, after determining a time difference between a predicted starting moment for the UE to receive a first data and a starting moment of a preconfigured first transmission resource for receiving the first data, if the time shift t3 is determined as a time shift which is closest to the time difference, a network equipment transmits an index corresponding to the t3 to the UE. After receiving the index, the UE determines the time shift t3 based on the index, and determines the time shift t3 as a time shift of the starting moment of the second transmission resource relative to the starting moment of the first transmission resource.
